Watermelon

Unlocks once you've harvested 540 Parsnip, 240 Kidney Beans, 150 Garlic and 140 Beetroot in all; unlocking it is then free.

A seed costs 35 spare parts and grows for 11m 40s (9m 20s on fertilized soil), needing water 6 times on the way: it stops growing until it's watered. It gives 14 harvests, growing back from scratch after each one.

Each harvest is one Watermelon and 17 spare parts: 238 from one seed, 203 more than it cost, over 2h 43m of growing. In a Biofuel Converter each one is worth 13 biofuel.

A Reaper chip can improve its grow time, watering, harvests, biofuel or earnings.
